두 개의 nsmutablearray 값이 서로 다른 값으로 바뀌고 있습니다.

Question

을 tableview textlabel에 넣고 NSMutableArray(self.dateListArray)을 detailtextlabel에 같은 인덱스에 삽입합니다. 처음에 올바르게 추가되었지만 TableView을 다시 열면 detailTextlabel이 textlabel으로되고 textlabel이 detailTextlabel이됩니다.

나는 NSLog 모두 NSMutabelArray이며 배열 값이 모두 바뀌고 있음을 알게되었습니다. 원래 값을 유지하는 방법? 제안에 대해 미리 감사드립니다. 은 왜 tableView == pdfListnameTable을 확인하는있는 tableView 코드

음, 확실하지 않지만 코드를 약간 리팩터링했습니다. 속성에 액세스하려고하는 것처럼 보이지만 인스턴스 값으로 액세스하려고하는 일부 장소가 있습니다.

그래서 여기에 내가 한 일이 있습니다. 정확하지 않을 수 있습니다. (또는 적어도 당신이 이것을 이해하는 데 도움이 될 것입니다)

으로 편집?

tableView isEqual:self. pdfListnameTable이어야합니다. 여기에 관련이 있는지 모르겠지만 하나 이상의 tableView가있는 경우 - 그 대신에 else 문이 없어 보이는 것처럼 전환하지 않는 것으로 추측 할 수 있습니다.
